SEMA / IGF-1 LR3 — 10 mg / 1 mg
$74.99
SEMA / IGF-1 LR3 denotes a proposed semaglutide–growth-factor combination. Semaglutide is studied for GLP-1-mediated metabolic effects, while LR3 IGF-1 supports growth signaling in laboratory systems; blend-specific claims require separate attribution. For research use only; not for human or veterinary use.
Full description
Educational research context. The cited studies and supplier descriptions do not verify the identity, testing, or effects of this Heritage product.
SEMA is a common abbreviation for semaglutide, a GLP-1 receptor agonist. IGF-1 LR3 is a modified form of insulin-like growth factor 1 used as a growth-promoting laboratory reagent. These components address different signaling systems: the semaglutide literature concerns metabolic regulation and body weight, whereas LR3 documentation emphasizes receptor-mediated cell survival and proliferation. The combined label does not identify a naturally occurring hormone or an approved fixed-combination medicine.
The STEP 1 trial studied semaglutide with lifestyle intervention in adults with overweight or obesity and reported greater average weight reduction than placebo. That study did not include IGF-1 LR3. GroPep’s LR3 product information concerns cell-culture supplementation rather than preservation of human muscle during semaglutide-associated weight loss. A possible body-composition rationale can be inferred from the pairing, but no exact Umbrella blend page or blend-specific trial was established in this review. Accordingly, descriptions such as fat loss with muscle support would need to be presented as a proposed combination concept, not as an outcome demonstrated by either component source.
